[Buildroot] Makefile for user applications

[Buildroot] Makefile for user applications

[Abhishek Ashtekar]

Hello,



I would like to add a precompiled/built application to the Linux 2.6.34.1 running on the at91sam9260ek board.

I have done the following steps

i)  Add  to /package   /package/myapp

ii)  introduce Config.in and myapp.mk and the application binary to the folder

iii) added   "source /package/ myapp/ Config.in"  line to the /package/Config.in and also select it through menuconfig



 Questions:-



 Actually I just want the makefile to copy the binary from the package to /targert/usr/bin

 However it goes to download myapp 1.0 Downloading ....... To a sourceforge.net  link and stops.

 What exactly do I need to mention in the make file ?



 Pasted below ....



#############################################################

 #

 # myapp

 #

 #############################################################

 MYAPP_VERSION = 1.0

 MYAPP _BINARY = myapp

 MYAPP _TARGET_BINARY =usr/bin/myapp



 MYAPP_INSTALL_TARGET = YES



 define MYAPP_INSTALL_TARGET_CMDS

            $(INSTALL) -D package/myapp/myapp  $(TARGET_DIR)/usr/bin/

 endef



 define MYAPP_CLEAN_CMDS

            $(MAKE) -C $(@D) clean

            rm -f $(TARGET_DIR)/usr/bin

 endef



 $(eval $(call GENTARGETS,package,myapp))

 #############################################################



Thanks a lot.



Regards,

Abhi

Yes, both the GENTARGETS and AUTOTARGETS infrastructure always download
the package source code if it's not already in the cache.

If you want a package that just copies a single tarball, you have to
make a manual Makefile.

Something like:

===================================================================
$(TARGET_DIR)/usr/bin/myapp: /somewhere/myapp
	install -m 755 $^ $@

myapp: $(TARGET_DIR)/usr/bin/myapp

ifeq ($(BR2_PACKAGE_MYAPP),y)
TARGETS+=myapp
endif
===================================================================

We might extend the package infrastructure in the future to support
this kind of thing.

Regards,

Thomas
